Faulty Parking Lights
Has anyone else come across this?? With the engine not running my parking lights function as they are meant to (in the UK anyway) with daylight running lights on (I think they may be dimmed as per in headlight on mode) and the rear lights on. When the engine is running however, the rear lights do not come on in 'parking light mode' . Jeep UK don't seem to have a fix, and my dealer noticed that a brand new Summit just arrived had the same issue too.
Not sure about the lighting requirements in the US, but in the UK parking lights 'on' should have front (parking) and rear lights on otherwise it would likely be an MOT fail (MOT is statutory annual test that starts from the car's 3rd birthday).
